Tip: Uncomment 5 favorite mirrors and place them at the top of the mirrorlist file. That way it's easy to find them and move them around if the first mirror on the list has problems. It also makes merging mirrorlist updates easier.

It is also possible to specify mirrors in /etc/pacman.conf. For the [core] repository, the default setup is:

[core]
Include = /etc/pacman.d/mirrorlist

To use the HostEurope mirror as a default mirror, add it before the Include line:

pacman will now try to connect to this mirror first. Proceed to do the same for [testing], [extra], and [community], if applicable.

Note: If mirrors have been stated directly in pacman.conf, remember to use the same mirror for all repositories. Otherwise packages that are incompatible to each other may be installed, like linux from [core] and an older kernel module from [extra].

Force pacman to refresh the package lists

After creating/editing /etc/pacman.d/mirrorlist, (manually or by using rankmirrors) issue the following command:

# pacman -Syy

Tip: Passing two --refresh or -y flags forces pacman to refresh all package lists even if they are considered to be up to date. Issuing pacman -Syywhenever changing to a new mirror is good practice and will avoid possible issues.

Mirror status

You can generate an up to date mirrorlist here, automate the process with a script, or install Reflector, a utility that generates a mirrorlist using Mirrorcheck's list; you can also manually check how up-to-date a mirror is by:

comparing the last-modified date of the i686 directory on the mirror to the [extra] date on the homepage, in the Package Repositories box to the right.

Sorting mirrors

When downloading packages pacman uses the mirrors in the order they are in /etc/pacman.d/mirrorlist. If not using reflector, which has the ability to sort mirrors by both how updated they are and their speed, follow this demonstration of manual mirror sorting.

Note: This does not apply to powerpill-light, which connects to many servers simultaneously to increase the overall download speed. The speed of individual connections becomes less relevant, and powerpill-light can be configured to require minimum speeds per connection.

List by speed

Take full advantage of using the fastest local mirror, which can be determined via the included Bash script, /usr/bin/rankmirrors.

Back up the existing /etc/pacman.d/mirrorlist:

# cp /etc/pacman.d/mirrorlist /etc/pacman.d/mirrorlist.backup

Edit /etc/pacman.d/mirrorlist.backup and uncomment mirrors for testing with rankmirrors.

Combined listing by speed and status

It is not a good idea to just use the fastest mirrors, since the fastest mirrors might be out of date. The preferred way would be to use #List by speed, then sorting those 6 fastest mirrors by their #Mirror status.

Simply visit either one or both #Mirror status links and sort them by the ones that are more up to date. Move the more up to date mirrors to the top of /etc/pacman.d/mirrorlist and if the mirrors are way out of date simply do not use those; repeat the process leaving out the outdated mirrors. So this ends up with a total of 6 mirrors that are sorted by speed and status, leaving out outdated mirrors.

When having mirror issues the above should be repeated. Or repeat once in a while even if not having mirror problems, to keep /etc/pacman.d/mirrorlist up to date.

Script to automate use of Pacman Mirrorlist Generator

You can use the following shell script to update your mirrors based on the rankings produced by the Pacman Mirrorlist Generator. If you do not live in the United States, you can change the country variable.

Note: You will need to copy the text above, place it into a file, and run chmod +x on the file. If you are not currently logged in as root, the script will invoke sudo for you when it needs to rotate the new mirrorlist into place.

Using Reflector

Alternatively, you can use Reflector to automatically retrieve the latest mirrorlist from the MirrorStatus page, filter the most up-to-date mirrors, sort them by speed and overwrite the file /etc/pacman.d/mirrorlist.

Choosing a local mirror

The simple way is to edit mirrorlist file by placing a local mirror at the top of the list. pacman will then use this mirror for preference.

Troubleshooting

Out-of-sync mirrors: corrupted packages/file not found

Issues regarding out-of-sync mirrors pointed out in this news post may have already been sorted out for most users, but in the event that problems of this nature present themselves again, simply try to see if the packages are present in the [testing] repository.

Doing so could help in any occasion where packages in the mirror have not been synced to [core] or [extra], and are still residing in [testing]. It is perfectly safe to install from [testing] in this case since the packages are being matched by version and release numbers.

In any event, it is best to switch mirrors and sync with pacman -Syy than resorting to an alternate repository. However, all or some of the mirrors may at times be out-of-sync to some degree.

Using all mirrors

To emulate pacman -Su's behavior of going through the entire mirror list, use this script:
